Spectrometer
C—Clear Buffer and Sample Time
Clears the buffer, accumulator, and sample time setting. Appends a line
feed (LF) character after the terminating carriage return (CR). Used only in
3310 APS™ spectrometer mode. Refer to the G command.
D—Dump
Performs a dump or all 78 channels (3310 APS™ spectrometer type). Data
beyond SCA calibration (max. of 52 channels), is reported as 0. Appends a
LF character after the terminating CR.
F—Fill Accumulators
Fills accumulators with x. If no x is provided it returns 1 or 0 to indicate
active or inactive. When active, an S1 command begins a sample of SMT
time and fill data is not cleared after each one second summation. If x=0,
then fill is disabled and data can be cleared. The pumps should be off or a
filter in place to prevent particles from being added to the fill data.
Fx
where:
x is 1–65535, but typically 10.
G—Go
Enables a 3310 mode sample.
Gx
where:
x is 1 to 65565 seconds of sample time.
In 3310 mode, the APS™ spectrometer runs without side-scatter and
acquires accumulator data. The command appends a LF after the
terminating CR.
H—Halt
Halts the 3310 mode. The command appends a LF after the terminating
CR.
